Mucuna (Mucuna Pruriens), also known as velvet bean and cowitch, is an herb used as a minor food crop and medicinal bean in India, West Africa, and Central America. It is indigenous to India and is a popular medicinal in that region. It is widespread over most of the subcontinent and can be found in bushes, hedges and dry-deciduous.

The pods of the Mucuna have hair-like needles covering the outside. These hairs contain mucunian and serotonin and can cause itching, blisters, and dermatitis. The hairs have been used in itching powder and mixed with honey to be used as vermifuge.

Mucuna can be a very beneficial supplement for bodybuilders. It is high in the amino acid L-Dopa which helps lower cholesterol and blood sugar levels. L-Dopa has been used as an anti-Parkinson's disease drug.

Another benefit of Mucuna, is that it can increase the production of HGH (Human Growth Hormone). An increase in HGH levels can increase the body's ability to build lean muscle and break down fat.

Mucuna has also been shown to have diuretic effects. It increases tissue resiliency and improves coordination. Mucuna can also increase testosterone levels, which in turn can lead to increased muscle mass and strength.

In history, Mucuna has been used as an aphrodisiac. It is still used to increase libido in both men and women, and can help with erectile dysfunction. It was also used to treat depression, nervous disorders, and to help improve mental alertness.
